TWO MATERIALS: The 2.3's frame is mostly Trek's Alpha Black aluminum, shaped to maximize the lightweight material's strength. The fork, seatstays, and post are carbon to help reduce the amount of road bump that reaches your body. The less vibration you feel, especially at the contact points of feet, hands and rear end, the less fatigued you'll becomeand the farther you'll ride. ALL GEARED UP: The dependable Shimano 105 crankset comes in two options: the gear-expanding triple or a compact double (a.k.a. the climber's little helper).Christine Bucher
